The carpometacarpal joint connects the carpal bones to the metacarpus or metacarpal bones which are joined at the intermetacarpal articulations. In the fingers, finally, are the metacarpophalangeal joints (including the knuckles ) between the metacarpal bones and the phalanges or finger bones which are interconnected by the interphalangeal joints .
The capsule of the joint is lax and extends from the inferior sacciform recess to the ulnar shaft. The DRUJ works with the proximal radioulnar joint (at the elbow) for pronation and supination. [5] The radiocarpal (wrist) joint is an ellipsoid joint formed by the radius and the articular disc proximally and the proximal row of carpal bones ...
The palmar radiocarpal ligament (anterior ligament, volar radiocarpal ligament) is a broad membranous band, attached above to the distal end of the radius, and passing downward to the scaphoid, lunate, triquetrum and capitate of the carpal bones in the wrist.
A Barton's fracture is a type of wrist injury where there is a broken bone associated with a dislocated bone in the wrist, typically occurring after falling on top of a bent wrist. [1] It is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint .
In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those of the metacarpus do. The corresponding part of the foot is the tarsus. The carpal bones allow the wrist to move and rotate ...

The wrist (Latin: carpus), [5] composed of the carpal bones, articulates at the wrist joint (or radiocarpal joint) proximally and the carpometacarpal joint distally. The wrist can be divided into two components separated by the midcarpal joints. The small movements of the eight carpal bones during composite movements at the wrist are complex to ...
